Communication Command Reference 99 99
Syntax PM:FREQuency?
Remarks The PM:FREQuency? query returns a value indicating the
present measured frequency in Hertz.
8.3.3.51 PM:Lambda
Description Wavelength set command
Syntax PM:Lambda value
Remarks The PM:Lambda command selects the wavelength to use
when calculating power. The value must fall within the
calibrated wavelength of the detector.
Argument Type Description
Value int Wavelength in nanometers (nm)
Related Commands: PM:Lambda?, PM:MAX:Lambda?,
PM:MIN:Lambda?
8.3.3.52 PM:Lambda?
Description Wavelength query
Syntax PM:Lambda?
Remarks The PM:Lambda? query returns the selected wavelength
in nanometers. This is the wavelength used to look up the
responsivity from the calibration data.
Response Type Description
Wavelength int Wavelength in nanometers (nm)
Related Commands: PM:Lambda, PM:MAX:Lambda?,
PM:MIN:Lambda?
8.3.3.53 PM:MAX:Lambda?
Description Maximum wavelength query
Syntax PM:MAX:Lambda?
Remarks The PM:MAX:Lambda? query returns the longest
calibrated wavelength in nanometers. If no detector is
preset, the max lambda for the last read detector is returned.
Response Type Description
Wavelength int Wavelength in nanometers (nm)
Related Commands: PM:MIN:Lambda?
